Thirty three male tudanca young bulls were used to evaluate 2 production systems (intensive and semiextensive) and 2 slaughter ages (12 and 14 months).
By means correlation and simple and multiple regression analysis, in this experiment were studied the correlation coefficients among the objective and subjective variables of the carcass and the relations between the weight of the main carcass cuts and the carcass weight.
The use of markers-derived metrics has been suggested to infer relative inbreeding from the homozygosity of markers. Automated genotyping systems yield accurate genotypes of multiple SNPs which are useful markers for this goal.
Among the autochthonous breeds in Spain, the Ripollesa sheep breed is the most common in Catalonia. It is rustic, with a convex profile, white wood of entrefine type and a characteristic pigmentation.
MESMIS methodology (Ridaura et al., 2002) has been tested to assess sustainability of two different commercial flocks within the breeding scheme of the Latxa sheep in the Basque Country.
A survey that gathered information about farm structure, grazing system, feeding and reproductive management was conducted in 181 farms. Parda de Montaña is the main breed regarding cows (92.4%), heifers (95,3%) and calves (84,1%).
Surveys were conducted to 141 farmers registered in the FERPAM at Asturias (A), Cantabria (C) and Castilla and Leon (CL) regions, with the aim to know animal production system characteristics.
The present work is part of an experimental program aimed to establish the dietary lysine (Lys) requirements of post-weaned Iberian piglets. For this purpose, we used 66 castrated male Iberian piglets of Silvela strain, with approximately 10 kg bodyweight and 40 days of age.
At present the Race Burguete is regarded as Breed in danger of extinction. The products marketed can be classified in Lechal (the colt once weaned enters the fattener) and Quinceno (foals that once weaned remain several months at grazing and around 15 months of age are fattening).
